In the past, the sea exploration sect would not set up a poison-absorbing array in their campsite. However, later on, when the sea exploration sect's people fought with the people of the sacred sect, they suffered a loss in this aspect. Many disciples of the sacred sect were poisonous demonic beasts. Even after they turned into human forms, they could release poisonous fog or venom. These things were very powerful and could cause a large area of casualties if they were not handled well. In addition, many of the sea exploration sect's disciples knew how to use poison. Sometimes, they would concoct poison in the camp. If they did not do it well and the poison was leaked, it would be a headache.
